No boost
So I noticed today that there is no psi being built in the motor. I ran some logs and the boost never got over .8 . I flashed the dme back to stock and have tried maos 1,2, and 5- still no whoosh.
Being that my car has been smoking, im thinking the turbos are shot, or at least close to. Any thoughts?

Check for boost leaks, and check for issues with boost solenoids and vacuum lines. Look down the left side of the engine bay, and you should see the wastegate actuator. Now watch the actuator rod as someone starts the car and gives it a few revs. You should see the rod move to activate the turbo.
Smoking isn't a great sign. |

Make sure it's not in the BEF mode. I think it's like menu 3 option 4 or something like that. If you can't figure it out let me know. My car was acting really funny one time when it accidentally got put in to BEF (back end flash) mode with out one loaded.
